SELFADJS-ITING IRESSRE SINK-FLUSHER,

Specification of Letters Patent.

Patented April 6, 1909.

Application filed December 26, 1808. Seii'al No. 469,322..

To all whom 'it may concern:

Be it known that I, WiLLiAM I-I. Dammen,

a. citizen ofthe United States of America', re-

sidin at Chester, in the county of Hancock and tate of West Virginia,- have invented certain new and useful Im )rovements in Self-Adjusting Pressure Sin Flusheis, of which the following is a specification, reference being had therein to the accompanyingrdrawings.

his invention relates to a self-adjusting pressure sink flusher, and the primary object of m invention is to provide a novel device by w ich the pressure of Water can be utilized for removing foreign matter and coagulations from a sink drain pipe or other drain `pipes Another object of my invention is to provide a simple7 durable and inexpensive iiush ing device that can be advantageously' used by landlords in maintaining the drain pipes of tenant houses in an open and sanitary condition.

My invention aims to provide a fhisher that can bc adjusted and clamped to the perforated plate or screen of a drain opening and confine above said perforated plate or screen, the pressurc` of water from a hot or cold water spigot, whereby the pressure of water will gradually remove foreign matter from the drain pipe that tends toY choke and pre vent the free passage of an ordinary flow of Water.

The device by which l accomplish this result comprises a hood and adjustable clamps for clamping the hood to the perforated plate of a sink. The hood is irovided with aA suitable connection adapted to be placed in engagement with a faucet or spigot for conveyingr pressure of water to the hood or x directly into the drain pipe for forcing the coagulation of said pipe through to the sewer mains.

The detail construction entering into my invention will be hereinafter described and then specifically claimed.

Figure 1 is a front elevation of a sink partlybroken away, illustrating the attachment in position for flushing the drain pipe of a sink, Fig. 2 is an enlarged vertical section of the flushingr device clamped to the perforated plato, and Fig'. 3 is a plan of the saine 5 with thc hose thereof detached.

In the accompanying drawings, 1 desig 55 natos a circular hood having a central boss 2 provided with awertical opening 3. The l peripheral edges ofthe hood 1 are reinforced, as at 4, vand the bottom edges thereof provided with an annular groove 5 for a resilient packing.; ring 6a.

Adjustahly mounted in the central boss 2 of the hood 1 is an exteriorly threaded pipe 6, and to firmly hold said pi e in engage-V ment with the boss 2 a wingr t iumb mit 7 is mounted upon said )ipe anda gasket 8 interposed between said nut and the boss 2 to form a non-leakable coimectionbetween the pipe and said'boss. The lower end of the pipe 6 within the hood 1l is provided with a nut Q having oppositely disposed threaded openings '10 formed therein adapted to aline with similar openings 11 formed in the lower end of the pipe 6. Adjustably mounted in the openings 10 and 1.1 are the threaded shanlis 12 of clamping members '13, said members having,r angular extensions 14. These clanniinpr members are adapted to eX- tend through the pcrforations 15 of a sink plate 16, with the angular extensions 1A eligaging undcr said sink late, while the resilient paclinir ring G of t ie hood is held in engagernent with the up )er surface of the plate 16 by the wingr thum nut 7.

The upper end of the pipe G is connected by a hose or flexible conduit 1T to a faucet oi' spigot 1S lorated in proximity to a sink 19. hen the faucet or spigot 18 is open, the. pressure of water is confined within the hood 1 and the drain pipe 20 of the' sink until the .foreign matter or coagulation therein cuts away and allows the water to freely pass through the drain pipe.

Since the pipe 6 can be adjusted with relation to the hood 1 and the clamping members 12 adjusted laterally relative to said pipe, the

flushingdf-vice can be easily clamped to the concave perforated plate irrespective of the location of the perfor-ations of said plate and to any pcri'oratml concave plate wherein the depth of the roneavity of said plate falls within the scope of the vertical ad justinent of the pipe Hot and cold water, steam and air under pressure can he utilized when convenient in lieu of a pressure of water -for cleansing a drain pipe or vsimilar structure obstructed by foreign matter.

While in thcdrawings forlninga part of this application there is illustrated the preferred embodiments of my invention, I would have it understood that the detail construction canbe varied or changed as to shape, 'proportion and manner ol assemblage without departing from the spirit of thy invention.

lHaving now described my invention what l claim as new, is:n

1. 1n a flusher, the combination with a perforated plate, of a hood mounted upon Said plate, a packing ring inter osed between the peripheral edges of said rood and said 2. In a iusher, the combination with af perforated plate, of a hood mounted uponl f# said plate, a vertical pipe adjustabl)r mounted in said hood, a nut carried by the end of said ipe within said hood, and clamping inemers adjustabl carriel by said nut for extending througii the perforations of said plate y perforated plate of a hood mounted upon :m

said plate, avertical pipe adjustablylnounted in said hood, clamping arms adjustably supported b f the lower end of said pipe withln lierforations of said plate and en 'age t der side thereof for holdingl saidH said plate.

4. In a sink liusher, the combination with a drain pipe havin a screen at the up )er end thereof, of. a hoo adapted to be el upon said screen, a pipe adjustably mounted in said hood for conveying water to said drain pipe,' and clamping members adjustably supported by said pipe within said hood and ada ted to engage in said screen for hood in enga ement therewith. In testimony whereof I ailix my signature in thelpresenee of two witnesses.
